Section 4 - FIRST AID MEASURES

SWALLOWED

• If swallowed do NOT induce vomiting.

• If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain open airway and prevent aspiration.

• Observe the patient carefully.

• Never give liquid to a person showing signs of being sleepy or with reduced awareness; i.e. becoming unconscious.

• Give water to rinse out mouth, then provide liquid slowly and as much as casualty can comfortably drink.

• Seek medical advice. EYE

If this product comes in contact with the eyes:

• Wash out immediately with fresh running water.

• Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and moving the eyelids by occasionally lifting the upper and lower lids.

• If pain persists or recurs seek medical attention.

• Removal of contact lenses after an eye injury should only be undertaken by skilled personnel.

SKIN

If skin contact occurs:

• Immediately remove all contaminated clothing, including footwear

• Flush skin and hair with running water (and soap if available).

POTASSIUM CHLORIDE

• Seek medical attention in event of irritation. INHALED

• If dust is inhaled, remove from contaminated area.

• Encourage patient to blow nose to ensure clear breathing passages.

• Ask patient to rinse mouth with water but to not drink water.

• Seek immediate medical attention.

NOTES TO PHYSICIAN For potassium intoxications:

• Hyperkalaemia, in patients with abnormal renal function, results from reduced renal excretion following intoxication.

• The presence of electrocardiographic evidence of hyperkalemia or serum potassium levels exceeding 7.5 mE/L indicates a medical emergency requiring an intravenous line and constant cardiac monitoring.

• The intravenous ingestion of 5-10 ml of 10% calcium gluconate, in adults, over a 2 minute period antagonises the cardiac and neuromuscular effects. The duration of action is approximately 1 hour. [Ellenhorn and Barceloux: Medical Toxicology]

Section 5 - FIRE FIGHTING MEASURES

EXTINGUISHING MEDIA

• There is no restriction on the type of extinguisher which may be used. FIRE FIGHTING

• Alert Fire Brigade and tell them location and nature of hazard.

• Wear breathing apparatus plus protective gloves for fire only.

• Prevent, by any means available, spillage from entering drains or water courses.

• Use fire fighting procedures suitable for surrounding area.

• DO NOT approach containers suspected to be hot.

• Cool fire exposed containers with water spray from a protected location.

• If safe to do so, remove containers from path of fire.

• Equipment should be thoroughly decontaminated after use. FIRE/EXPLOSION HAZARD

(4)

(6)

POTASSIUM CHLORIDE

• Always wash hands with soap and water after handling.

• Work clothes should be laundered separately.

• Use good occupational work practice.

• Observe manufacturer's storing and handling recommendations.

• Atmosphere should be regularly checked against established exposure standards to ensure safe working conditions are maintained.

SUITABLE CONTAINER Glass container.

Multi ply paper bag with sealed plastic liner or heavy gauge plastic bag NOTE: Bags should be stacked, blocked, interlocked, and limited in height so that they are stable and secure against sliding or collapse. Check that all

containers are clearly labelled and free from leaks. Packing as recommended by manufacturer.

acids.

STORAGE REQUIREMENTS

• Store in original containers.

• Keep containers securely sealed.

PERSONAL PROTECTION

EYE

• Safety glasses with side shields; or as required,

• Chemical goggles.

• Contact lenses may pose a special hazard; soft contact lenses may absorb and concentrate irritants. A written policy document, describing the wearing of lens or restrictions on use, should be created for each workplace or task. This should include a review of lens absorption and adsorption for the class of chemicals in use and an account of injury experience. Medical and first-aid personnel should be trained in their removal and suitable equipment should be readily available. In the event of chemical exposure, begin eye irrigation immediately and remove contact lens as soon as practicable. Lens should be removed at the first signs of eye redness or irritation - lens should be removed in a clean environment only after workers have washed hands thoroughly. [CDC NIOSH Current Intelligence Bulletin 59]

HANDS/FEET

Wear general protective gloves: i.e. Disposable polythene gloves or Cotton gloves or Light weight rubber gloves, with Barrier cream preferably Safety footwear.

ENGINEERING CONTROLS

None required when handling small quantities. OTHERWISE:

Use in a well-ventilated area.

• Local exhaust ventilation is required where solids are handled as powders or crystals; even when particulates are relatively large, a certain

proportion will be powdered by mutual friction.

• Exhaust ventilation should be designed to prevent accumulation and recirculation of particulates in the workplace.

• If in spite of local exhaust an adverse concentration of the substance in air could occur, respiratory protection should be considered. Such protection might consist of:

(a): particle dust respirators, if necessary, combined with an absorption cartridge; (b): filter respirators with absorption cartridge or canister of the right type; (c): fresh-air hoods or masks

• Build-up of electrostatic charge on the dust particle, may be prevented by bonding and grounding.

• Powder handling equipment such as dust collectors, dryers and mills may require additional protection measures such as explosion venting.

Air contaminants generated in the workplace possess varying "escape" velocities which, in turn, determine the "capture velocities" of fresh circulating air required to efficiently remove the contaminant.

Type of Contaminant: Air Speed: direct spray, spray painting in shallow

booths, drum filling, conveyer loading, crusher dusts, gas discharge (active generation into zone of rapid air motion)

1-2.5 m/s (200-500 f/min.)

grinding, abrasive blasting, tumbling, 2.5-10 m/s (500-2000 f/min.)

POTASSIUM CHLORIDE

high speed wheel generated dusts (released at high initial velocity into zone of very high rapid air motion).

Within each range the appropriate value depends on:

Lower end of the range Upper end of the range 1: Room air currents minimal or

favourable to capture 1: Disturbing room air currents 2: Contaminants of low toxicity or of

nuisance value only 2: Contaminants of high toxicity 3: Intermittent, low production. 3: High production, heavy use 4: Large hood or large air mass in

motion 4: Small hood-local control only

Simple theory shows that air velocity falls rapidly with distance away from the opening of a simple extraction pipe. Velocity generally decreases with the square of distance from the extraction point (in simple cases). Therefore the air speed at the extraction point should be adjusted, accordingly, after reference to distance from the contaminating source. The air velocity at the extraction fan, for example, should be a minimum of 4-10 m/s (800-2000 f/min) for extraction of crusher dusts generated 2 metres distant from the extraction point. Other

mechanical considerations, producing performance deficits within the extraction apparatus, make it essential that theoretical air velocities are multiplied by factors of 10 or more when extraction systems are installed or used.
